[Pkg-gmagick-im-team] Bug#772603: imagemagick:amd64 installation fails with imagemagick-6.q16:i386

[Frédéric Brière]

Package: imagemagick
Version: 8:6.8.9.9-3
Severity: important

[ CCing the submitter of #761836, which I'm guessing is the same bug. ]

I'm getting an error when attempting to install/configure imagemagick:

  # dpkg --configure --pending
  Setting up imagemagick (8:6.8.9.9-3) ...
  update-alternatives: error: alternative path /usr/bin/compare-im6 doesn't exist
  dpkg: error processing package imagemagick (--configure):
   subprocess installed post-installation script returned error exit status 2

This is because the targets of the symlinks under /usr/bin are meant to
match with imagemagick-6.q16 of the same architecture:

  $ readlink /usr/bin/compare-im6
  ../lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/compare

But imagemagick-6.q16 is marked Multi-Arch: foreign, so the dependency
may be satisfied from a different architecture:

  $ dpkg -s imagemagick imagemagick-6.q16 | egrep '^(Package|Arch)' 
  Package: imagemagick
  Architecture: amd64
  Package: imagemagick-6.q16
  Architecture: i386

  $ dpkg -L imagemagick-6.q16 | grep compare
  /usr/lib/i386-linux-gnu/ImageMagick-6.8.9/bin-Q16/compare
